Letters Patent No. 113,463, dated April 4, 1871. I

The Schedule referred to in these Letters Patent and making part of the same.

We, \VILLIAM' H. ST. J OHN, of the city of Broolc- Nature and Objects of the Inrcntion.

The nature of our discovery or invention consists in the introduction of mechanical appliances into aseries of pipes, as set forth, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

To enable others skilled in ihe art to make and use our discovery and invention, we will proceed to describe its construction and operation.

General Description.

, First, the gas, afterleavingthe hydraulic main, is conducted by an ordinary pipe, A, fig. 1, front elevation, to the condenser, where it enters compartment B, at the end of the tar-well I), and is conducted down to the hydraulic seal 0, of one-half to three-quarters of an inch, which gives to it the first friction on entering the condenser.

It is claimed that the seal 0, in connection with the lattice-work G, and corrugated plates I, and corrugated covers J, precipitates all the tar existing in the volume of gas after leaving the hydraulic main.

Second, the gas beingforced thronghvthe seal O by the exhauster into compartments B, and after leaving this compartment it enters the first series of the condenser; its course is then changed by coming in con-, tact with the iron plate E, which is sealed in the tarwell 1), as shown in fig. 1, and, rising in the vertical pipe F, is passed between the corrugated surfaces of lattice-work G, which, being adjustable, is opened and closed at pleasure by the lever H, to secure the necessary amount of friction desired.

county of Third, the upright pipes F are ofa rectangular form, and divided into several compartments by the introduction in section of corrugated plates I. These plates are held in their places by small projections or brackets cast on the inside of the pipes F; also in three or four lengths, so as to be easily taken out for any repairs that mayhe necessary.

Fourth, the covers J are made of corrugated iron, and are fitted into a cup, K filled, with 'waterof a given depth, to correspond with the seals, siphons, and cups of the purifiers, 850., and are held in their positions by a strap-hinge, fastened with a pin, and are adjustable, so they can be removed to clear any ob structions that may in time occur.

Fifth, the gas, after passing between the latticework G, is divided into separate volumes by the corrugated plates 1, and, rising in the-pipe F to the top, is carried across to the opposite pipe F by the covers J, and enters-it, and descends to the tar-well D. It

then moves forward on this same side until it comes in contact with a corresponding iron plate, E, which causes it to enter the pipe F, and passes between a similar lattice-work, G, and corrugated plates I, ascends to the next cover J, by which it is brought across to the opposite pipe F, and again descends to the tar-well D, and so on, alternately, until it passes through the whole of the condenser into the main L, and is conducted to the purifier.

Sixth, the lattice-work G is secured in a framework, l), which is bolted to the bonnet d, and slides into the pipes F upon projections or'grooves cast on the inside of the pipes F, and is further supported by a horizontal reversing-bar, 71, which projects through the stuffing-box c, so as to receive the handle H, by which it is moved to the desired position'to secure the amount of friction necessary upon any volume of gas that may be passing, which is determinedby the graduated arc f upon the bonnet (Z, and the pressuregauges M attached to the inlet and outlet of the condenser.

Seventh, the inner end or the horizontal bar It is pro per and lower tiers of slats G by means of parallel bars.

0, secured to the pins which. rotate the slats G.

The lattice-work G is secured to. the frame-work b that is bolted to the bonnet d, 'which is fastened by tap-bolts to the vertical pipes F, and is easily removed for any repairs or cleaning that maybe needed by opening the valves 0' and shutting off the gas from the condenser by the valves N, and passing it through the by-pass P, as shown in the plan, fig. 3. It is also located at the base of the pipes F, in which the gas ascends, which is alternately on eaclnside of the condenser.

,airni (tffioz.

The corrugated lattice-work G, or slats, have upon their ends a journal or ,pin, whiclrworks in a loose s0o ket, aud are moved by the action of the parallel barsc abode described.

The bases of the pipes-1* are enlarged in proportion to the room occupied by the lattice-work G, so that their area is maintained.

The sections of corrugated plates I in the pipes F are placed alternately overthe intermediate space of the section below, in order .to divide the'volume of gas into separate columns,, thus distributing and-securing greater amount of friction, and are supported cubic feet, more or less, per day, and will arrest all of What we claim as our invention, and desire to se- I sure by Le-tters Patent, is

1. The application-of the hydraulic seal to the whole rolume of gas at the entrance of the condenser.

2. The adjustable lattice-work and appliances.

3. The corrugated plates dividing the vertical pipes in compartments also, the corrugated covers as herein described,

and substantially set forth in the spec-
